In serious car sound installations, there is an increase in external supporter. Let's get pregnant what are the automobile powertrains, what is their advantage? And we will forget about such pardons.

On the radio, you can add the numbers “4 x 50W” - this is the maximum intensity that can be seen at the peak of the signal (for a short hour). When nonlinear conflicts add up to 10%, this is no longer music. The speakers easily play two dozen watts, which are supplied by the power-assisted magnetols. Ale itself 10-20 W, not 50! The nominal tension of the head devices varies at the boundaries. It's a tightness if the music doesn't wheeze and squeak.

Types of boosters for subwoofer and speakers

Automotive dual-channel boosters. They are used for the clear and powerful sound of a pair of speakers or one subwoofer. Why one? The subwoofer is responsible for producing low frequencies (below 60-100 Hz), and the stench is not localized. Therefore, you can get by with one subwoofer, connecting up to two channels simultaneously in mono mode (bridged connection). When the bridge is connected, the tension, which appears to be stronger, will be much greater.

For the butt. Since a two-channel subwoofer has a nominal output of 2x60 W, when connected in bridge mode the output output is 1x200 W. To “sub” gravitate low frequencies, use a boost filter low frequencies. Without him, all the music will turn into “bubble” from the trunk. Inside the mouth of the acoustics, you need to go around - tidy up the low ones.

Why are there single-channel boosters? This is a one-piece product and there is no wide range through specificity. Single-channel boosters are used in professional audio systems if the maximum volume of the subwoofer, and not its sound, is important.

The widest possible channel boosters- for their popularity, the stinks deserve due to their versatility. The widest connection scheme is two channels for the front speakers and two channels for the subwoofer. So we immediately connect the speakers and the subwoofer, and if there is none, we connect the rear speakers. There is also a “per-channel” connection - one pair of outputs goes to the “eager”, the other goes to the speakers.

What types of acoustics connection schemes there are are described in the article: “Using a music system in a car.”

We were re-trimmed through tri-channel boosters. Also, the third channel is used to connect a subwoofer. It is impossible to establish a tri-channel sales force, because His multi-channel “amplifiers” were recognized through their versatility.

What's the fuss? five-channel boosters- in essence, these are several channels with an additional channel for the subwoofer. Since everything with the “bass” channel is clear, then you can select both for a system with front and rear speakers, and for the “channel”.

Buy a supplement - correct it, the other half - install it. The housing and wiring are securely fixed. Don’t forget about natural ventilation - everyone warms up. I remain: If one booster on-board system survives without wasting money, then you will have to deal with a lot of tight, powerful folds.

Many car owners without technical knowledge do not know how to connect the booster to the car radio - for them this is not a difficult task. In fact, it’s not a good idea to rush to a car service center, since installing a car booster is not so difficult. Technical maintenance by specialists will be expensive, so to save money, you can try to understand the connection procedure, which will help with this article.
For efficient work of the booster it is necessary:

Tax on the new garne of food;
Turn over so that the signal comes from the car radio;
Connect the speakers or subwoofer.

You can read the report on how to connect the booster below.

Garne food is the key to success

The procedure for connecting a power booster begins with power darts. Conduction is the most important element of a car audio system, as it is responsible for the richness and bitterness of the sound. For those who are strong, a stable meal is required, which in other times of exertion will not be enough, through this sound we will become satisfied. In order to understand that it is necessary to pay attention to the strength of the wiring and how it flows into the sound that is created by the Guchnomovets, it is necessary to find out what a musical signal is. They assume that it is a sine, however, the musical singal is characterized by a large difference between the primary and peak values. While sharp signal spikes are not important for the dynamics of car acoustics, the situation is completely different. If the signal would like to exceed the permissible strength for a second (or even a millisecond), then these “anomalies” will be a clear warning for those who cannot boast of a good ear for music.

If the connection of the car booster has been properly installed, the signal is sent through the wires in an undisturbed view. The operation may be damaged or improper selection of wire cuts will result in the sound being more compressed, rough and squeaky. In some seizures, you may also wheeze slightly.

Yak vibrati peretin drotu?

The wire is the original metal that provides support to the rhubarb. The lower the wire is, the lower the support is. In order to minimize sound loss during periods of strong voltage changes (for example, during periods of heavy bass), it is necessary to install a wire of the required caliber.

Warto note that the crossbar of the positive cable is not to blame for more than the negative one (the difference in which does not matter).

It is customary for people to rely on electrical devices. For new effective work It is necessary to have a clear grounding so that it is possible to extract the required energy from the battery.
To select the wire spanning correctly, it is necessary to carry out the following steps. To begin with, read the instructions before the booster (or directly on the box from the distributor, since there is no documentation, use the Internet) and find out there the values of the nominal strength (RMS). Nominal voltage is the voltage of the boost signal, which can last for three hours per channel at 4 Ohms. If you look at the different channel boosters, they will have a power output of 40 to 150 W per channel. It is possible that the booster you mentioned has a power of 80 watts. As a result of awkward mathematical operations, it is clear that the total power of the power supply is 320 W. Tobto. How did they praise you? Everything is simply multiplied by the nominal pressure by the number of channels. Since our dual-channel booster has a nominal power supply (RMS) of 60 W, the total becomes 120 W.

After you feel tired, it is important to determine the maximum amount of power from the battery to your booster and you can quickly consult the table to select the required power supply. How to use a table? On the left side, the strength of your support is indicated, on the right hand, select the second part, go up the hill and find out what kind of crossover you need.

The table shows the cutting of copper wires, remember that there are a large number of wires that are sold, we cover them with aluminum, these wires are not durable and have a larger support, it is recommended in and corrode the copper wires.

Vibe of a devotee

In order to ensure the connection of the car booster, it is necessary to ensure the protection of the power supply from the battery to the booster for the auxiliary driver. The culprits must be placed closer to the battery. It is important to separate the device that protects the device itself (either the power supply or the radio) and the device that is installed on the power cable.

The remaining one is needed in order to steal the cable itself, which is why the smallest string goes to it.
Reconfirm that the value of the connections has been avoided, since the value of the wiring connection will be even greater, then as a result short shimmer The wire may burn out. If the denomination, however, is less, then at the moment of peak pressure it can easily burn out and then there will be no other way out but to buy a new one. The table below shows the cut-off value and the required denomination of the beneficiary.

Connects interblock darts and ceramic (REM)

To lay the cable, you need to know the line output on the radio. The line output can be recognized by the characteristic “links” located on the rear panel of the radio. The number of line outputs varies for different radio models. Name them as one to three pairs. Basically, they are divided into 1 pair - you can connect a subwoofer or 2 speakers (signatures as SW\F) If you have 2 pairs, you can connect 4 speakers or a subwoofer and 2 speakers (signatures F and SW), and when tape recorders 3 pairs of line You can connect 4 speakers and a subwoofer (F, R, SW) F Front is the front speakers, R Read is the rear speakers, and SW Subwoorer I think and so everyone understands.

To connect, you will need an interblock wire, which cannot be saved at all times. It is advisable to install an interblock cable around the power wires, since during engine operation there will be slightly different interruptions. You can stretch the darts both under the rims of the interior and under the frame. The remaining option is especially relevant for current cars, in the salon there are changes made to the electronic device.

It is also necessary to connect the ceramic emitter (REM). As a rule, when going at the same time with interblock wires, otherwise there will be something and nothing, add it as needed so that a large cross-cut of 1 mm2 is completely sufficient. These wires serve as controls for turning on the booster so that when the radio goes off, your booster or subwoofer automatically turns on. As a rule, this wire on the radio is blue with a white background, if there is none, then use the blue wire. Connect the line to the power supply to the terminal called REM.

Connecting a dual-channel and multi-channel booster

We have combined these sections, because these boosters have a similar connection scheme, so we can say more simply, there are four channel boosters - there are two dual-channel ones. The connections of the dual-channel booster are not visible to us, but if you figure out how to connect both channels, then you won’t have any problems with the dual-channel connections. Most car enthusiasts choose this option for their installations, since to this power supply you can connect 4 speakers, or 2 speakers and a subwoofer. Let's take a look connections for four channel support vikorystyuchi first and other options.

It is recommended to connect the 4-channel booster to the battery using an additional thick cable. How to select the correct power arrows and connect interblocks, we have all figured out more. The connection of the power supply must be indicated in the instructions from the operator. When the booster is connected to the acoustics, it operates in stereo mode, in this mode This type of booster can be operated under voltages ranging from 4 to 2 ohms. Below is a diagram of connecting a multi-channel booster to the speakers.

Now let's look at another option, if speakers and a subwoofer are connected to the multi-channel amplifier. In this case, the booster operates in mono mode, but take the voltage from two channels, so try to select a subwoofer that supports 4 ohms to save the booster from overheating and the input is protected. Connecting a subwoofer is not a problem; as a rule, the radio requires the plus sign to connect a subwoofer, and the minus sign. Take a look at the diagram of how the bridge connection of a 4-channel booster works.

Connecting a monoblock (Single-channel booster)

Single-channel power amplifiers are only suitable for one channel – connection to the subwoofer. An important characteristic of exercisers of this type is increased effort. Monoblocks are also available with a support lower than 4 ohms, which is called low-impedance voltage. Monoblocks are classified as class D, and they have a special filter for cutting frequencies.

Installing a single-channel booster does not require a lot of effort, and some of its connection circuits are very simple. There are two outputs - “plus” and “minus”, and since the speaker only has one coil, it is enough to just connect it to it. As far as connecting two speakers is concerned, they can be connected either in parallel or in a sequential way. It is very important to separate at least two speakers, but before that connect the booster and subwoofer to the radio, which will connect with the remaining support.

This will help you create more useful information on the site.

The visibility of the subwoofer can be easily adjusted to the robot acoustic system car, but it will only be possible for correctly connected until podsiluvach. Unfortunately, this operation is far from being as simple as it sounds. In order for everything to work correctly, it is necessary to set a number of important parameters. In this article, we will try to figure out how to properly connect the subwoofer to the booster.

The first step is to connect the active and passive subwoofer to the booster, you can set the RMS value (depending on what you can do with the real one). sound signal protyag Godini without poshkodzhen) subwoofer and pіdsiluvach. It is necessary to select the device in such a way that this parameter will be stronger than that of the subwoofer. Otherwise it is possible to shift acceptable level tightness (clip), which is one of the most common types of speaker failure.

For optimal robot The pressure of the subwoofer and the subwoofer is almost equal.

What is required to connect?

To connect the subwoofer to the booster, you first need to check what you need. To install a subwoofer and booster in a car you will need:

Dial terminals and connectors;
Video to sound converter;
Linear devotee;
Peremikach for remote living;
Capacitor;
A set of darts for connecting a subwoofer and booster, which are selected for a specific acoustic system.

To get the required set of darts, you just need to go to any store that sells sound systems for cars, and tell them your car model and radios.

The amount of darts is calculated according to the selected subwoofer to booster connection circuit.

Carrying out the conduct

Before installing the subwoofer and booster, you must take note of this, and the auto booster itself will be installed. At the chosen location, you need to place the edge of the live wire and place it under the hood of the car. For this purpose it is necessary to maintain a supply of thirty centimeters.

Some machines already have openings with rubber or plastic inserts, which are used for carrying out an acoustic system. If the opening needs to be drilled, extreme care must be taken to avoid damaging important components and parts. In some places, the wiring must be additionally covered with electrical tape.

Life of the podsiluvach

Now it is necessary to ensure life for the auto driver. To do this, you need to connect the battery cable to the vehicle's power cable and connect it to a new power cable. After this, without connecting the power cable to the battery, you need to insert it into the main power supply cable, and then connect it to the battery.

Grounded

The next step in installing the subwoofer and booster into the car will be grounding. For this purpose, it is necessary to carry out a thorough preparation of the bare metal (low-fat, unsalted and without traces of corrosion) metal. Before connecting the wood, sand the selected section. Most often, you simply unscrew one of the seat bolts, attach the ground wire to it, and tighten the bolt.

Connecting the power supply to the radio

Naturally, connecting a subwoofer through a booster would be noiseless without affecting the sound of a car radio.

We first need to secure food in the distance. Non-original car radios usually have a blue wire, which you can simply cut and connect in place of the new power cable.

If you have an original radio, you need to buy a suitable jumper and find a place in which to place and play the following:

Stretch the wire from the booster until the jumper;
Cut it in half;
Connect the ends to two terminals;
Move the cut part back, leaving a margin of 30 cm.

Next, it will be necessary to connect a capacitor, which will help reduce the voltage cuts through the voltaic preswitch connected to the strong bass. The capacitor is liable to grow closer to the power supply, violating its grounding.

Once the capacitor has completed its function, it needs to be charged. For this purpose it is necessary to select a resistor with a support of 1 kOhm. Charging will take just a few seconds, but better yet, don’t touch anything with your bare hands. Checking the charge of the capacitor is done using a voltmeter, which may show close to twelve volts.

Next, you need to connect the signal pins to the linear outputs of the radio. This number can reach up to six, although in multimedia centers there can be more. We select the outputs and connect them to the power supply using interconnect cables. For two-channel models, separate interconnects are required.

Since the radio has only one pair of linear outputs, and the auto booster has several channels, it is necessary to use Y-adapters. However, most current boosters offer the possibility of parallel connection of inputs, which allows you to do without them.

In order to connect the subwoofer to the power supply, we need an audio converter - a small box with two RCA outputs and 4 wires. Two darts are required to connect the speaker, what you have lost can simply be taken back out of respect. The wire for the RCA output is connected to the power supply.

How to connect a subwoofer to a single-channel amplifier

Connecting a subwoofer to a single-channel amplifier is a simple operation. It is necessary to solder the “+” and “-” output to the “+” and “-” subwoofer.

Much more complex connection passive subwoofers. For this purpose parallel and sequential schemes are used. However, in this case it is necessary to properly open the support.

How to connect a subwoofer to a dual-channel booster

The connection is made using a “bridge” - this method works effectively with almost two-channel amplifiers, until you need to connect one subwoofer. To do this, you need to take “+” from one channel and “-” from another, which we connect directly to the subwoofer.

An important point is that when connected, the power supply is no less than ohms. In addition, it should be noted that in such a situation, the output tension of the channels will be assumed.

If the booster can switch mono and stereo modes, you can simply connect the switches to “+” and “-” to one channel. In case you need to connect 2 subwoofers to the booster, you just need to separate them into different channels.

It is also important to remember that for correct operation of the subwoofer it is necessary to turn on an LPF filter, which is lower than the frequency above 50-100 Hz.

The classic way to connect car speakers to a multi-channel amplifier is a circuit with two speakers and one subwoofer.

So, how can you connect a subwoofer and speakers like this?

The standard option would be to connect two speakers and one subwoofer. The skin column is connected to local channel At that time the subwoofer is installed as a bridge. An important point is that the speakers will be connected to the front channels, and the subwoofer to the rear ones.

It is also possible to separate two subwoofers adjacent to the same power channels.

Dual-channel car amplifiers for rich people become a kind of bypass in the world of car audio, since two-channel amplifiers are inexpensive and often used in budget systems as a booster for front speakers and subwoofers. Let's look at the main options for connecting a dual-channel booster.

Option one – we connect acoustics.

In such a circuit, the majority of power boosters normally operate from voltages up to 2 ohms. Tobto. You can connect a pair of four-homed acoustics to the skin channel.

Another option is to connect a subwoofer.

Another expanded option for connecting a dual-channel amplifier is working with a subwoofer in the so-called “bridge” mode.

Almost all dual-channel boosters can operate in this mode. You connect “+” to one channel of the booster, for example the left one, and “-” to another channel, for example, the right one in our circuit. Sometimes the booster needs to be switched to brook, or the mono mode will be switched to a remixer. The connection diagram can be found on the booster body or in the instructions. Please note that the bridge mode has 99% of subordinates Do not apply pressure below 4 ohms!

It’s amazing for many of the world’s car owners to know how expensive it is to equip them with various accessories and technical maintenance. Either for the sake of economy, or for the love of technology, you can do everything with your own hands that does not require special expensive equipment.
Instructions and videos on the pages of our website will tell you how to connect the subwoofer and booster to the car radio. The food price should be set most often.

What is the booster needed for?

In addition, as soon as the connection is made correctly, the sound will be brighter. There are various options for connecting the stereo sound or audio system in the car interior.
Otje:

If you are not affected by the heavyness of your car radio or the intensity of the sound generated by it, you can choose power with the help of a support professional. Of course, the equipment is not at all the same as that found in sound systems that operate under 220 volt electricity.
A passenger car only has one battery, while a van or a bus has two – 12V each.
The axle for such a low-tension measure is insured by boosters for cars. How does a stink cause obvious tension?
On the right is that there is a voltage converter built into the car booster. Zalezhnoe vіd technical characteristics If you change a specific device, for an additional pulse, you can move the voltage from 12 to 100 volts.
Well, the strong man will independently provide himself with the necessary stress.

Criteria for selecting a support worker

Like any other technology, the car radio has different characteristics. As long as it is connected and operates in the same system with other equipment, their performance is most suitable for regular use.
Therefore, before you connect the booster to the car radio, be sure to carefully read and complete the following data:

One of the most important technical characteristics of the booster is the amount of pressure per channel. So, when purchasing a booster, this indicator must be compared with other indicators to decide ownership.
You absolutely need to know what the nominal volume of your main speaker is, as well as the dynamics of the subwoofer itself. Their indicators of tension slightly overestimate the tension of one channel of the booster.
This allows you to extract the clearest sound possible. In addition, such a range of pressures will overcome the pressure of the speakers, and there will definitely be no wheezing and stench.
Another important characteristic of a supporter is support. The main requirement for support is an acoustic system.
Tom characteristics given It is necessary to be equal to the dynamics and boost (for example: and there, and there 4 Ohms). It’s completely normal, since the demand for speakers will be even greater.
If it turns up unexpectedly, there is every chance that during operation both the booster and the dynamics will go wrong. The frequency range in a car booster is no less than 20 Hz – 20 KHz.
Well, this range will be even larger.

Today's automobile engines have such an element as a crossover. It allows you to use boost in different modes, as well as frequencies in different ranges.
They also have a transit line output, which allows you to connect another booster if necessary.

How to select when a subwoofer is installed

Various modifications to these settings and their selections depend on the configuration of a particular sound system:

Let's say you have a subwoofer installed. In this case, a two-channel booster is required, and buying it, it is necessary to convert what can be done with a bridge connection method. Before speaking, there are a lot of such boosters.

Bridging means that two power channels drive one subwoofer speaker. If the bridge connection for the amplifier is not transferred, you need to think about how to connect the amplifier and subwoofer to the car radio, so that the signal is lost.
Fahivtsi with car audio often go into songful tricks. It is possible to combine the two channels as one whole, subsuming the output signal. This connection is made when a signal is sent to a subwoofer with a dual voice coil.
In this case, the output channels, with the same polarity, are connected to the subwoofer windings. Well, if the winding is in one, special sumators are used.
The result is a mono signal, the strength of which is equal to that of one channel, minus the associated costs.

This is a foldable option for connecting the power supply to the subwoofer. When the cutaneous strengthening channel is closed, it works, and then the signal is detected.
The frequency ranges of the channels in this case do not need to be shifted so as not to overpower the boost. For this purpose, a passive filter is installed at its output.

Come to the hour of sounding

The connection of the booster to the car radio should be made because at high volume the sound will be subject to extraneous noise and the speakers will wheeze.
Otje:

As a rule, this is not the case if the smell is immediately reached by the booster installed in the car radio. There is little tension, and it’s as if the horn is singing to you.
What does it reach, for example, forty watts, please note that the pressure is peak, not sound.
A rich-channel booster can correct the situation. And even better, if you connect 2 boosters - the car radio, almost any kind of speaker, transmits a series of similar sound circuits.

To connect to the rear panel of the radio, linear RCA outputs are transmitted, and there can be either one or more. However, with the simplest and most inexpensive options for car radios, there may be no outputs at all.
In this case, the booster is connected to the speakers (div.), not directly, but through a special device that changes the amplitude of the sound. It's called an attenuator.
The copy price of this device allows you to buy it from any radio electronics store. If you want, you can vikoristovat the old detail, well, that the attenuator of awakenings in the skin is used and the TV.
Power supply response: “How do I connect 2 boosters to the car radio?” I’ll say goodbye if you come out after all.
The simplest way is that there are two RCA outputs. They may be needed for sub-connection to the front and rear speakers.

The front and back come out, at your drawer, they can also be loosened - and then you will need not two, but several roses. If there is only one outlet for the power supply, you will need to install a special cord with necessary quantity rozgalen.
People call such a cord a tulip, as you can see in the photo of the animal. If you connect two boosters, the connection to the front may or may not work.

What is required to connect?

How to connect the booster to the car radio, or more precisely, what kind of power do you need? This nutrition is even more important, and we will try to inform you in the next report.
Otje:

Let's take a look at the necessary set of darts that may be needed during the connection process. The product itself is the source of life.
Its tension is selected as follows: the tension of all channels of the booster is assumed, since there are two of them, then, naturally, the tension of the other is taken into account.
Let’s say you plan to install two dual-channel boosters: one of them has a channel intensity of 40 W, and the other has a channel intensity of 30 W. And here, the power of all channels is set to: 40*2+30*2= 140 W.
We add 30% to this figure and add 182 watts. This very tightness will be felt by the tensioners at maximum tightness, and it is necessary to select the wire span according to this value.
We divide the total tension by the voltage at the limit (182W/12V=15.17A), and we determine the maximum possible strength of the stream.

The cross section of which will be filled with the singing power of the strum, this is the main table of the performance of all cable products. As soon as you tell the consultant in the store your number, they will immediately tell you what kind of wire you need.
Our version for 15A requires a copper wire with a crossbar of 0.75 mm2. You can take the cable from three pieces with a larger crosspiece.
There will be a reserve - for the occasional connection to the future tightening of sound control.
The sound supply from the car radio to the booster operates via an additional interconnect cable. Of course, there must be some bitterness in the sound.
And if you hope to protect yourself by buying a thin cable, with weak insulation and rotten screens, don’t wait for receiving signals when listening to music.

The interblock or signal wire is made of heavy shielding, tight insulation, a thick central core and a bright RCA connector. If there is any problem with any cable, it needs to be unwrapped so that it can be laid around the cabin without tension.

Ale y zaiva dovzhina is not required - one meter of reserve is enough. Take the interconnect cable in two copies.
Another wire will be an additional wire that you will need during the connection process. Let's say more about this.

You will also need a devotee. This tension is to blame for the rash display of tension.
Our unit has 15A, so the zabobizhnik needs to buy at least 20A. Well, you can buy a flask for a devotee, whatever suits your special needs.

We connect the power supply

As a rule, the driver forces you to move around the trunk. The exact location you choose is up to the authorities to decide.
Make sure that it is dry there and that the attachment does not heat up. Once the location has been selected, proceed to laying the wires.
Otje:

First, under the car trim, from the booster to the radio, lay a signal cable. There is no clear conclusion here, because the gasket options are selected depending on the make and modification of the car.
It is only necessary to remember that the interconnect cable is not prone to wire sticking. side bars, which is under stress. The additional wire, which we talked about earlier, is laid simultaneously with the signal cable.

From the battery to the booster, stretch the life wire. It can be laid in parallel before the car is installed.
Place the trimmer flask from the storage tank, which is in the new one, close to the battery - the wiring between them should be as short as possible.
The signal cable is connected to the connectors: on the radio it is called Line-Out, and on the amplifier Line-in. Conducting life will also arrive until support.
What's the fuss? additional cable, which is extended at the same time with the interblock cord: on the power supply, it is connected to the Remote connector. It turns on the booster at the hour of supplying the +12A power supply.
On the car radio, this wire is connected to the blue color B+Ant.

Let's stay at this process Connections to speakers are possible. When using the booster, the first channel of the booster is connected to the positive terminal of the dynamics, and the other to the minus terminal.
The bridge connection diagram has been drawn up.
To this end, a small device called a storage capacitor is installed. This device helps the on-board system to get back to the necessary settings, as a result of the operation of additional sound equipment.
The main purpose of the capacitor is to protect the booster from voltage drops at the boundary.
For example, when the voltage is reduced, it increases the strength of its reserve, and thereby improves the capacity of the sound. Connect this device on the terminals of the living quarters, using the shortest possible wires. Don't forget about the pre-trimantic polarities!

Before speaking, such a capacitor is installed on the subwoofer, and also in addition to the power supply. Then you will only have to work on setting up the booster according to the instructions of the operator.
The adjustment process is individual, and depends not only on the modification of the magneto and booster, but also on the presence and absence in the subwoofer system.
